Read remote file with node.js (http.get)

Question

Read remote file with node.js (http.get)

Whats the best way to read a remote file. I want to get the whole file (not chunks).

I started with the following example

var get = http.get(options).on('response', function (response) {
    response.on('data', function (chunk) {
        console.log('BODY: ' + chunk);
    });
});

I want to parse the file as a csv, however for this I need the whole file rather than chunked data.

Thank you

Answer 1

I'd use request for this:

request('http://google.com/doodle.png').pipe(fs.createWriteStream('doodle.png'))

Or if you don't need to save to a file first, and you just need to read the CSV into memory, you can do the following:

var request = require('request');
request.get('http://www.whatever.com/my.csv', function (error, response, body) {
    if (!error && response.statusCode == 200) {
        var csv = body;
        // Continue with your processing here.
    }
});

etc.

http.get(options).on('response', function (response) {
    var body = '';
    var i = 0;
    response.on('data', function (chunk) {
        i++;
        body += chunk;
        console.log('BODY Part: ' + i);
    });
    response.on('end', function () {

        console.log(body);
        console.log('Finished');
});
});

Changes to this, which works. Any comments?
